I believe that cloud version is up to date, though you could just use Bleeding Edge for the most stable version.

I play Destiny 2 all the time, and I believe it's the game as well. Bear in mind that hit detection is largely due to other players lagging. When you've got players from far away connecting you'll find that they're either harder or easier to kill.

I believe Destiny 2 changed their server setup to allow more distant players to join, since the amount of people playing Destiny 2 is quite low at the moment.
